I had another developer here install Netbeans and follow the same guide and
he had the same exact results.

We are both running Windows and use Xampp/pear/phpunit on command line to
test currrently due to the fact that it will not work in Netbeans.

I had previously tried this in Linux (Fedora 13/14) and had the same results.
The bug report mentioned above is not the same and is not at all related. The
bug mentioned by paolosca is a bug regarding Selenium server not getting
installed. In my case it is installed and running when I start Netbeans as
seen by may last test and the fact that I see port 4444 open when it starts.

Can anyone tell me if this is a bug?
Have I done something wrong?

I followed the calculator guide/test and phpunit works up until you tell it
to run the selenium test.
